Sartorius, CUB2.7S-1S3-F, Cubis® III Ultra-Micro Lab Balances

Cubis®III ultra-micro balances are designed for laboratories that demand the highest level of precision, flexibility, and process reliability. Engineered for micro-weighing tasks, they combine cutting-edge weighing technology with intelligent software to deliver trustworthy results even at the smallest readability levels. Typical applications include filter weighing, pipette calibration, and weighing of the smallest sample amounts. At the heart of each Cubis®III ultra-micro balance is a highly stable weighing system with excellent repeatability and minimal drift over time. Advanced compensation algorithms and optimized mechanical design help minimize the influence of temperature fluctuations, vibrations, and air currents. This ensures that users can reliably achieve accurate measurements in environments that are often less than ideal, such as busy analytical labs or production-adjacent quality control areas. The Cubis®III ultra-micro balances feature intelligent automatic functions—such as motorized glass draft shield, automatic taring, guided cleaning and built-in leveling support—simplify routine tasks and help reduce handling errors. The high-resolution touchscreen eases the daily work with guided workflows, where users can select predefined methods, input sample IDs, and document results with just a few steps. The software is easily expandable with compliance features and advanced connectivity options. Cubis®III ultra-micro balances are built with data integrity and regulatory compliance in mind. Comprehensive user management, audit trail, and electronic documentation functions support operation in regulated environments, including laboratories subject to GMP, GLP, and 21 CFR Part 11 requirements. Connectivity options, such as Ethernet and USB interfaces, enable seamless integration into laboratory information systems and digital data workflows, reducing manual transcription and the risk of errors. With their combination of mechanical robustness, outstanding measurement performance, and smart software features, Cubis®III ultra-micro balances provide a reliable foundation for critical weighing tasks. They support scientists and quality professionals in achieving reproducible results, optimizing their workflows, and meeting the stringent standards of modern analytical and quality laboratories.
